You should know that dual-booting multiple versions of windows on the same hard drive without having external backup or Cloud storage backup is
NO BUENO!!
Very risky!
If that Hard Drive or Motherboard crashes in that computer, you are quite likely to lose massive amounts of your data if not all of it.
You have a single-point of failure on that computer with all of your large Word files and years of images. We suggest that you buy a large flash drive or an external hard drive; either which can be had for well under $100 on ebay, amazon, or newegg.com. Cheaper than your Car or Homeowner's insurance, right?? How much is that stuff worth to you, financially?
How many hours and how much effort would be required to replace it, if that were even possible???
You should think about having at least 2 different types and locations of backups. One backup can be done on local media such as a flash drive or external hard drive, and another on a Cloud Storage account such as Microsoft OneDrive or GoogleDrive. These Cloud accounts usually will give you 100GB to 1TB for free; if you need more than that you can purchase it online with a Credit Card for about
$20/yr. or so.
Might be worth thinking about, as I've been doing dual-boot systems for 25 years; and they are indeed much riskier than single-boot systems. You need to make up your mind which Windows version you want to stick with and re-do your computer with that one (W7 or W10)!!
When I worked at IBM and had 70 field engineers, many of them had dual-boot or multi-boot setups on their laptops. They crashed so often, that our Regional Tech Director made us stop issuing laptops to the FE's like this, as we had a whole roomful of techs fixing those things 40 hrs. per week and doing no other productive work! Something to keep in mind.
